Connect problem when hostname=computername but no problem when IP?

I have ORA-12541 problems to connect to a (local) Oracle XE installation when TNSNAME contains
a computername (e.g. “maggie”) as hostname.
When I enter/replace the hostname by the corresponding IP (e.g. 127.0.0.1)
then connect works immediately.

So I guess there is a problem for Toad to convert computername to IP

What’s wrong? Actually I prefer to use computernames at least for remote machines.

How can I help Toad (under 64bit Win7) to find the refering IP?

I don’t think that’s Toad, I think that’s your network. Can
you ping ‘maggie’?

127.0.0.1 is localhost, not a remote machine, but I’m guessing you knew
that already.
